IMPROVEMENT IN GOVERNORS FOR ENGINES.

Spec'ification'forming part of Letters Patent No. 216,922, dated June 24, 1879; application filed April 23, 1879.

To all whom it may concern:

Be it known that I, SAMUEL WHINERY, of Wheeler,in the county of Lawrence andState of Alabama, have invented a new and useful Improvement in Governors for Engines, of which the following is a specification.

The object of my invention is to construct a governor for marine or other engines in which the usual variations of speed will be controlled by centrifugal balls, and any sudden increase or decrease of speed checked in-' stantly by an independent movement of the .same mechanism.

In the accompanying drawings my invention is shown in connection with a centrifugal governor.

Figure l is a front elevation. Fig. 2 is an elevation at right angles to Fig. 1. Fig. 3 is an elevation of the worm-gearing in larger size.

Similar letters of reference indicate corresponding parts. V

Upon a standard, a, in bearings b b is fitted the vertical spindle c of a centrifugal governor. The spindle 0 passes loosely through bearings 11, and carries upon its upper end the springs d and balls c,'fitted to operate spindle c by centrifugal action, in the usual manner. 'The lower end of spindle 0 is connected by a :swivel-joint to the rod f, that actuates the governing-valve of the steam or a variable cut-.

lofl' device, as may be desired.

Upon the spindle 0, below the upper bearing, lb, is affixed a worm-gear, g, that meshes with an oblique-toothed or worm pinion, h, which is secured to a cross-shaft, i, journaled in boxes formed in the fixed frame of the governor. Upon shaft i is a driving-pulley, k, by which the governor will be driven.

l is an adjustable weight on a lever, m,that is fulcrumed on the governor-frame. The inner forked end of L takes beneath the gear g, to regulate the position of spindle 0. Around the spindle 0, above the bearing b, is a spiral spring, m, preferably steel, and fitted for be ;ing compressed more or less by an adjustable :nut and washer, n.

The action of the governor will be as folilows: Motion being given to pinion h by pulley k, the worm g, spindle c, with the attached from any cause, start suddenly with increasedspeed, the impulse would be communicated instantly to pinion it, Which, not being capable of overcoming the inertia of the balls and'increasing their velocity uddenly, will act on worm g in the manner a rack and pinion, thereby forcing the wormand spindle 0 downward and cutting err the steam to the required extent. This downward mothm of the spindle will at the same time force the balls outward and maintain them there until the equilibrium of the parts be restored.

Underreverse conditions,when the engine, by

asuddenly-imposedload, is suddenly slackened in speed, the inertia of the balls would impel them for a time at the rate of speed previously acquired; but the rotation of pinion It being checked, the worm g, acting against the cogs of it, will carry spindle c upward and open the steam-valve, and at the same time draw the balls inward.

By adjusting counterpoise-weight Z the parts may be regulated for the desired normal action.

By the above-described construction the governor will be rendered extremely sensitive and the movements nearly uniform. The sudden impulses of the engine will be checked before the jerk can. have any effect.

It will be seen that the mechanism acting to check the sudden changes'is between the engine and the usual governor, and does not act through the governor; but the steam is out 01f before the impulse has acted upon the centrifugal governor.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. As an improvement in engine-governors, pinion, h, asset forth, of the spiral springm, the combination, with the parts fitted for censubstantially as and for the purposes specitrifugal action, substantially as described, of fied. the Worm-gear operated upon by the pinion,

substantially as described, and for the pur- SAMUEL WHINERY poses set forth. i Witnesses:
